The Art of Pace - Judgement: An entirely new angle on training and racing for the runner, whether champion or novice. by Guy Butler. 

Printed by Vail & Co., Ltd., London. Undated, circa 1950. 24 pp. Scarce.

I'm assuming, but don't know for sure, that the booklet is by gold medal Olympian, British sprinter Guy Butler. After his retirement from competitive running he coached for some time and worked as an athletics correspondent. 

Book will be carefully packaged and shipped in a cardboard book wrapper.
